Today, July 18th, is the beginning of Denver’s largest and longest running festival of its kind. The UMS boasts more than 400 national and local entertainers over a long and eventful four-day event. It has become a city staple in the music community, taking over a solid mile of the popular South Broadway shopping and dining district.

Moving from a one-venue event at The Bluebird to “SoBo” in 2006, the UMS now commands over 25 different sites along the popular stretch. The scene will take place starting at 8:00 p.m. tonight and run through to Sunday July 21st – the last of the bands hitting stage around 11:00 p.m. Sunday night.

Artists this year include Cults, Mudhoney, Ian Cooke, Snake Rattle Rattle Snake, The Epilogues, A Tom Collins, Small Black, In The Whale, Monroe Monroe, BLKHRTS, Hockey and hundreds more. The High Plains Comedy Festival Showcase will also be on deck, providing comedic entertainment outside of the unending musical performances. Jordan Doll, Kristin Rand, Bobby Crane and Ben Roy are a few that are scheduled to appear.

There’s a lot to keep organized. To make the daunting task of scheduling the weekend a bit easier, the people over at the UMS have also just recently launched a smartphone app that’s available for both the Android and iOS systems. The utility allows you to preview bands before their performances, keep a personalized schedule on hand and it even follows popular social media sites for the official #ums2013 tracker.

Tickets are $50 for a 4-day wristband or $120 for the VIP badge and as of today are still available at the box office. Visit the official site of the Underground Music Showcase for updated information.
